Ad-hoc Poll

Quantitative surveys involve the use of structured questionnaires developed and customized to the client’s needs by professionals of economics and marketing. The main aim of quantitative surveys is to poll a certain portion (sample) of the target group using a structured questionnaire and, having analysed the obtained data, to generalize the results for the whole population.

When are surveys conducted by face-to-face interviews (F2F, PAPI, CAPI)?

Face-to-face interviewing is used when the target group is hard to reach by telephone and internet or when the aim of the research is to carry out a representative survey. This method is also handy when a survey is complex, long and involves additional means (e.g., visual material).

When are surveys conducted by telephone (CATI)?

Telephone interviewing is used when the target group is easy to reach by telephone (e.g., company managers, doctors, clients of a company, etc.) and the survey is short and does not involve visual material. The population is also polled by telephone using quota sampling.

When can surveys be conducted on the web (CAWI)?

Web interviewing is used when the target group is very specific and uses the internet, i.e., the number of internet users in the target group is sufficient to ensure data validity. Web interviews are conducted using panels (interactive database of respondents, who have given prior consent to participate in surveys).
